This video is a lecture that explains the relationships between wave speed, wavelength, and frequency of a wave. It starts by defining a transverse wave and discussing the amplitude, wavelength, frequency, and time period of a wave. The...

In this video, we use the following equations to interconvert between and do calculations with Frequency (λ), Wavelength (𝝂), & Energy: 1) E=h𝝂 2) 𝝂=c/λ 3) E=hc/λ

In this video Paul Andersen explains how the wavelength is the distance between oscillations in a wave. In a longitudinal wave this might be the distance between areas of compression. In a transverse wave it might be the distance between...

The video explains the concept of redshift and blueshift in the context of galaxy movement and how it relates to the shift in wavelength of light emitted by a galaxy. The video then shows how to use an equation to calculate the shift in...

This video discusses the properties that all waves have in common, including amplitude and wavelength. It also demonstrates how to calculate the speed of a wave using the equation v = Fλ, where v is the wave speed, F is the frequency in...

Particle-on-a-Ring Example #2: Calculate Energy, Wavelength, and Momentum

This video explores the characteristics of waves. It explains the speed of waves, how this value is calculated and the four basic interaction between waves. Other terminology includes: vibration, crest, trough, amplitude, wavelength,...

With the Bohr model we start to get a better sense of the nature of matter, particularly the way light interacts with atomic matter such that we can see it. But how do we do calculations regarding these interactions? Let's practice now!

In this video Paul Andersen explains how matter can act as a wave at the nanoscale. Louis de Broglie showed that the wavelength of matter can be calculated using the momentum of an object and Planck's constant. The Davisson-Germer...

The wave model of the electron can be used to explain the Bohr model. Electrons are found in certain orbits because they interfere with themselves and create standing waves. When the wavelengths don't match up with a whole integer they...

In this video Paul Andersen explains how the wave speed measure the speed of a wave through a medium. The medium determines the speed of the wave. The velocity of the wave is equal to the product of the wavelength and the frequency of...

This video explains how to conduct an experiment to determine the speed of a wave on a string. It shows the steps involved, such as setting up the string or wire, creating a wave on it, and adjusting the distance between the two ends to...

A key tool in atomic physics is the hydrogen spectrum, which shows the quantised energy levels of the electrons in a hydrogen atom. The electrons in hydrogen gas absorb energy and travel to higher energy levels when the gas is excited,...

This video is a lecture on how waves change as they cross the boundary between different materials, also known as changes of medium. The video explains what a medium is and how it affects wave propagation. The video uses examples of...

This video discusses the importance of absorption spectroscopy. A brief idea about ultraviolet and visible spectroscopy is presented in the video. The video shows the light sources used for different regions of operations. The type of...

Wave Equation | Waves | Physics | FuseSchool Waves have a frequency (the number of complete waves passing a point every second and measured in Hertz), wavelength (the distance between two consecutive points on a wave) and amplitude - the...

The video explains two important features of a wave: the frequency and the time period. It uses a visual representation of a transverse wave and a longitudinal wave to show the peaks, troughs, amplitude, and wavelength of a wave. The...

Wave Motion | Waves | Physics | FuseSchool All waves can transfer energy from one place to another without transferring any matter. This is done by a series of disturbances or vibrations that carry the energy. Just like the people in...

Paul Andersen explains how natural selection is a major mechanism in evolution. The video begins with a discussion of Charles Darwin and the details of natural selection. The data of the peppered moth during the industrial revolution...

In this video Paul Andersen explains how the amplitude of a wave is a measure of the energy of the wave. He gives several examples of wave amplitude and shows you how to calculate the wave of a transverse and longitudinal wave.

When Ernest Rutherford realized that atoms have a heavy nucleus, he hypothesized that the way the moon orbits earth is the same as the way an electron orbits the nucleus of atoms. We now know an atom would...

When the nucleus was discovered by Rutherford, it became clear the classical world was not reality, because according to classical electromagnetism, the electron should collapse to the proton. This problem was...

Bohr's model of the atom says that an electron's energy is set by its orbit around the nucleus. Bohr said that electrons have specific, quantised levels of energy, and that the size of the orbit affects the energy...

The video is a guide on how to conduct an experiment to determine the speed of waves on water using a vibrating object and a ripple tank. The video explains the setup of the ripple tank and the use of a DC electric motor to generate...
